          Fierce fightings over Stawki Street last the whole day. The warehouses pass from hand to hand multiple times.

          At 5:30 pm the Germans launch a re-attack along the section of Leszno Street. The infantry, supported by three tanks, cross the barricades on Leszno and Przyjazd Streets and captures Rymarska Street. As a result of the counteroffensive of the troops commanded by Second Lieutenant "Kuba", the area lost by the insurgents during the day falls again into their hands in the evening.

          The troops under the command of Major Stanisław Błaszczak "Róg" ("Horn") repel German attacks on Powiśle, on the barricades erected on Kanonia, Świętojańska, Miodowa and Piwna Streets, and on the Town Hall and the Blank Palace.

          Fires are ravaging the dense urban area of the Old Town.

          The Germans introduce "goliaths" into the combat.

          The RONA troops recapture the buildings of the Water Supply and Sewerage Directorate at 5 Starynkiewicza Street, the Tourist House, the Municipal Institute of Hygiene at 82 Nowogrodzka Street, the Military Geographical Institute on Aleje Jerozolimskie and the buildings of Starostwo Grodzkie (County Office) near Nowogrodzka Street, the corner of Chałubińskiego Street.
          The "Chrobry II" group maintains control over the north side of Aleje Jerozolimskie with the Railway House and the Post Railway Station.

          Thousands of people are massacred in Ochota - bombarded with grenades in cellars, executed at the gates and in squares. Drunk soldiers bayonet the old and sick. Hundreds of women are raped and murdered. The Germans commit bloody acts of massacre in St. Jacob Church and in the Radio Institute.

          The Home Army Headquarters move from the school on Barokowa Street to the building of the Ministry of Justice at 7 Długa Street.

          On the night of 11 and 12 August the Germans shoot down an Allied plane delivering supplies. The burning machine plummets down on the Praga's bank of the Vistula River.
